<p>A hold and release mechanism for holding and releasing a cable includes a toothed-disk arrangement coupled with the cable take-up device for rotating together about a first axis. The toothed-disk arrangement includes a plurality of teeth at an outer periphery of the toothed-disk arrangement. The plurality of teeth includes locking and safety teeth. The locking teeth are disposed in a first tooth plane orthogonal to the first axis. The safety teeth are disposed in a second tooth plane that is orthogonal to the first axis and offset relative to the first tooth plane. An adjustable locking pawl pivotably mounted about a second axis includes locking and safety catches. The locking catch engages with one of the locking teeth for holding the toothed-disk arrangement in a first rotational position. The safety catch engages with one of the safety teeth for holding the toothed-disk arrangement in a second rotational position.</p> |
